6 Step Espalier Fig Training Routine with Brown Turkey on a Warm Wall

Fix the wires before the fig goes in

Put the support on the wall before planting. Use galvanised vine eyes driven well into the masonry, the longer screw-in type that bites into a plug rather than the short hammer-in kind, spaced about 45cm apart vertically to carry tensioned 12-gauge wire. A useful frame has three or four horizontal runs, starting roughly 40cm above the soil and finishing near 1.8m, so the plant has proper tiers instead of a loose fan. Fit straining bolts at one end. After one season with growth leaning on the wires, slack usually appears.

Keep the wire off the brick by 8 to 10cm. That gap leaves room for air behind the shoots, so the wall face dries after rain and the lower leaves carry less fungal pressure. It also gives enough clearance to pass ties around a shoot without pressing soft wood against cold masonry. The wall is there to radiate stored warmth into the fruiting zone; a shoot held flat against damp brick can rot where it touches.

Brick and rendered block suit this job better than timber fencing. Their mass holds daytime heat and releases it overnight, and that overnight floor temperature helps embryo figs carry through to the following summer. A thin larch-lap fence stores almost nothing, however neatly it has been wired.

Confine the roots

A fig in open ground often spends years making canopy with very little fruit. The traditional English answer is a lined planting pit: paving slabs on all four sides, roughly 60cm by 60cm by 60cm, with rubble or broken brick at the base. The slabs check the roots and the rubble forces drainage. With less root freedom, the plant is pushed toward fruiting instead of making the large, loose growth that quickly overruns a wall.

A large container can do the same work when digging a pit is too slow or awkward. Sink a 45 to 50 litre pot to its rim beside the wall. It restricts the root run like slabs do, and it can be lifted or inspected more easily. The cost is water. A confined root ball beside hot masonry dries fast in summer, and a fig that wilts again and again will drop developing fruit. Drip irrigation on a timer covers the worst of that gap.

Backfill with a free-draining loam in place of a rich compost. John Innes No 2 mixed with horticultural grit, at about one part grit to four parts compost, gives structure without overfeeding. Excess nitrogen produces soft growth that frost kills and whitefly love.

Make the first winter cut low

Plant a maiden whip or a young two-year tree against the central vertical. In the first dormant season, cut it back hard to a bud about 40cm above the soil, just below the lowest wire. It looks severe on a plant you have just bought, yet that cut is what makes the lower tier possible. A fig allowed to keep its leader will run upward and leave the bottom wires bare for years.

As shoots break in spring, keep three. One continues vertically toward the next tier; two are trained left and right along the bottom wire. Rub out the rest while they are still soft. Tie the laterals at a shallow angle at first, around 45 degrees, then lower them closer to horizontal as they extend through the season. Once a shoot lies flat, its pace slows and fruit buds are favoured over more extension growth.

Pinch when the fifth leaf opens

Fig shoots crop best when stopped early. Once a young breast-wood shoot has five expanded leaves, pinch out the growing tip back to the fifth leaf. On a wall-trained Brown Turkey, that small summer job often separates a fruiting frame from a leafy one.

Read the crop before you prune

Brown Turkey carries two possible crops, and cool-climate pruning depends on knowing which one is likely to ripen. The breba crop forms on the previous year’s wood and swells early in the season. The main crop sets on current-season growth. In most British and northern European gardens, the main crop does not receive enough heat to finish. The figs picked from a wall-trained plant are therefore almost entirely breba figs, the small embryos that overwintered no larger than a pea.

Any main-crop figs larger than a hazelnut by late autumn are unable to ripen or survive winter. They rot, drop, and use the plant’s energy on the way out. Remove them. The tiny embryo figs at the shoot tips, about peppercorn size, are the ones to keep. They sit tight against the stem through winter and begin swelling again in spring. If the small embryos are stripped off while the doomed larger fruit is left behind, there may be nothing to pick the following July.

Stopping a shoot at five leaves lets light reach the breba figs lower down, while also encouraging embryo figs to form near the tip, where they overwinter best. Light is part of what colours and sweetens the fruit. A congested espalier that has not been pinched shades its own crop, and the figs can remain green and dull into September.

Watering changes the result more than feeding. Brown Turkey wants steady moisture from fruit-set until the figs begin to soften, followed by a drier spell during ripening. If a dry fortnight is followed by a sudden heavy soak, the skins can split. A split fig in damp August air can mould within a day. A 5cm surface mulch of leaf mould laid in spring steadies the soil moisture and cuts down hand watering through July.

Frost is the other variable. The overwintering embryos tolerate a few degrees below zero against a warm wall, but a hard, prolonged freeze can kill them. In exposed gardens, horticultural fleece over the lower tiers during the coldest weeks protects the crop already set for next year.

The state of the fruit in autumn shows where the plant put its season. Big late figs are growth that came too far behind the climate to finish, and they are also the embryos at the shoot tips, no bigger than peppercorns, that hold the chance of next summer’s pick.

Thin the frame as it ages

An established espalier needs winter thinning as well as shaping. Cut out any shoot growing straight out from the wall toward you, since it will not lie flat and will shade the tiers below. Remove crossing wood and anything crowding the centre. Aim for a fan of well-spaced laterals, with light reaching the full frame.

Older Brown Turkey plants often send vigorous water shoots from the base and from old cuts. Most should come out, although one or two well-placed shoots can replace a tired tier. Tie the chosen replacement in over a season, then cut the exhausted branch back to it the following winter. Renewing the structure gradually keeps the wall covered while the underlying framework is rebuilt.

Fig sap bleeds from cuts and can irritate skin in sunlight. Heavy structural pruning is best kept for late winter, when the plant is fully dormant and sap flow is slowest. Smaller summer pinching can be done with fingers and causes no real bleeding.

Where the wall stops helping

The warm wall has limits. In the coolest gardens, a carefully trained Brown Turkey may still ripen its breba crop and lose the entire main crop every year, and pinching cannot change that. What stays out of the gardener’s hands is the wall itself in April and May, when the embryos try to restart and the overnight warmth held in that particular run of brick decides how many of them wake up rather than blacken and drop.
